10. CALIBRATION
The scale can be calibrated using the following procedure.
For a more
detailed method of calibrating the scale it will be necessary to enter the
secure Programming Menu. Refer to the CTB Service Manual for more
information.
The CTB scales calibrate using metric weights and the CTBa scales can
calibrate using either metric or pound weights, depending on the
weighing unit in use before calibration.
The display will show either
"kg" or "lb" to identify the weights expected.
Turn the power off. Turn the power back on, during the counting from 9 to
0 press the SET key.
The display will show "CAL " for a few seconds. While it is showing
"CAL " press the SMPL, PRINT and TARE keys in sequence to enter
the Calibration section. The display will show "unLoAd".
Remove any weight from the platform. Press the ZERO/ENTER key.
The display will show "LoAd". Place the calibration weight on the scale.
Press the ZERO/ENTER key.
The display will show the last calibration weight used. If this is correct
you can continue by pressing the ZERO/ENTER key.
If it is not correct
use the arrow keys to change the calibration weight value. When it is
correct press the ZERO/ENTER key.
If the calibration is acceptable the display will show "PASS" and then
return to normal. If an error message is shown try calibration again as a
disturbance may have prevented a successful calibration.
If the problem persist then contact Taiwan scale or your dealer.
After calibration the scale should be checked to verify the calibration and
linearity is correct. If necessary repeat calibration, especially be certain
the scale is stable before accepting any weight.

8. BATTERY OPERATION
The weighing indicator can be operated from the battery if desired.
The battery life is approximately 100 hours.
When the battery needs charging a symbol on the weight display will
turn on. The battery should be charged when the symbol is on. The
scale will still operate for about 10 hours after which it will
automatically switch off to protect the battery.
To charge the battery simply plug into the mains power. The scale does
not need to be turned on.
The battery should be charged for 12 hours for full capacity.
Just under the weight display is an LED to indicate the status of battery
charging. When the scale is plugged into the mains power the internal
battery will be charged. If the LED is green the battery has a full charge.
If it is yellow the battery is nearly full of charge and red indicates the
battery is being charged.
As the battery is used it may fail to hold a full charge. If the battery
life becomes unacceptable then contact your distributor

-6Place a container on the platform, a value for its weight will be
displayed. Press the TARE key to tare the scale. The weight that was
displayed is stored as the tare value and that value is subtracted from the
display, leaving zero on the display. The "TARE" indicator will be on. As
product is added only the weight of the product will be shown. The scale
could be tared a second time if another type of product was to be added
to the first one. Again only the weight that is added after taring will be
displayed.
When the container is removed a negative value will be shown. If the
scale was tared just before removing the container this value is the gross
weight of the container plus all product that was removed. The zero
indicator will also be on because the platform is back to the same
condition it was when the ZERO/ENTER key was last pressed.
3.3 Weighing a sample. To determine the weight of a sample first tare
the empty container then place the sample in the container. the display
will show the weight and the units of weight currently in use.
4. Parts Counting
When the scale is showing weight, pressing the SMPL key will start
the parts counting function.
Before beginning, tare the weight of any container that will be used,
leaving the empty container on the scale. Place the number of samples
on the scale. The number should match the options for parts counting,
10, 20, 50, 100 or 200 pieces.
Press the SMPL key to begin. The scale will show "SP 10"
asking for a sample size of 10 parts. Change the sample size by
pressing the TARE/ key. the display will cycle through the options:
10,20, 50, 100, 200 and back to 10.
Press the ZERO/ENTER key when the number matches the number
of parts used for the sample.
As more weight is added the display will
CTB weighing indicator operation manual
REV C1, June 2012
-3show the number of parts (pcs).
Press the FUNC key to return to normal weighing.
5. Check-Weighing
Check-weighing is a procedure to cause an alarm to sound when the
weight on the scale meets or exceeds values stored in memory. The
memory holds values for a high limit and a low limit. Either limit can be
used or both can be used.
See PARAMETERS SECTION for the procedure to be used to set
the limits, function "F0 H-L" is used. After limits have been set the
Check-weighing function is enabled.
When a weight is placed on the scale the arrows will show if the
weight is above or below the limits and the beeper will sound as
described below.
BOTH LIMITS SET
The display will show OK and the beeper will sound when the
weight is between the limits.
LOW LIMIT SET,
HIGH LIMIT is set to zero
The display will show OK and the beeper will sound when the
weight is less than the Low Limit. Above the Low Limit the
display will show HIGH and the beeper will be off.
HIGH LIMIT SET,
LOW LIMIT is set to zero
The display will show LOW and the beeper will be off when the
weight is less than the High Limit. Above the High Limit the
display will show OK and the beeper will be on.
BOTH LIMITS SET. LOW IS SET GREATER THAN HIGH
The beeper will never sound and the display will show LOW if the
weight is less that the LOW limit, and HIGH if
CTB weighing indicator operation manual
-4the weight is greater than the Low Limit.
NOTE: The weight must be greater than 20 scale divisions for the
checkweighing to operate.
To disable the Check-Weighing function enter zero into both limits by
pressing the FUNC/C key when the current limits are shown then
pressing ZERO/ENTER to store the zero values.
6. Accumulated Total
The scale can be set to accumulate manually by pressing the PRINT
key. See the PARAMETERS Section for details of selecting the method
using function "F5 PRT". The accumulation function is only available
when weighing. It is disabled during parts counting.
The weight displayed will be stored in memory when the PRINT key
is pressed and the weight is stable.
The display will show "ACC 1" and then the total in memory for 2
seconds before returning to normal. If the optional RS-232 interface is
installed the weight will be output to a printer or PC.
Remove the weight, allowing the scale to return to zero and put a
second weight on. Press the PRINT key, the display will show "ACC
2" and then the new total. Continue until all weights have been added.
To view the totals in memory press PRINT key in zero point.
To clear accumulation memory press enter the PARAMETER
SECTION and use function "F1 TOL". See below.
7. PARAMETERS
The scale has 6 parameters that can be set by the user plus a
method of entering the calibration section.
To set parameters press the FUNC key.
The display will show the first function, "F0 H-L".
Pressing the TARE/+ will cycle through the other functions.
